I know, this doesn't look like much of a frenzy but we have more hummingbirds this year than I can ever recall. This feeder is on the patio and I only see one hummingbird on it. However, on the north side of the house, outside our kitchen window, is where the action is. We have counted at least 8 hummers at one time and in past seasons only one or two. I added a second feeder to alleviate the traffic and it just seems to be growing. They are so much fun to watch.
